EDWARD ANDREVS, OF POTTSVILLE, ASSIGNOR OF ONE-HALF TO ROBER H. COLEMAN, OF OORNWALL, PENNSYLVANIA.

VlB'RATlNG-CYLINDER ENGINE.

SPECIFICATION forming part of Letters Patent No. 354,762, dated December 2l, 1886.

Application filed September 2P, 1886. Serial No. 214,777. (No model.)

To @ZZ whom t may concern.-

Be it known that l, EDWARD ANDREWS, a citizen of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Vibrating-Cylinder Engines; and l do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled ro in the art to which it appertains to make and use the same.

My invention relates to that class of engines in which the cylinder is seated at one end in a concave seat and vibrates with the movei 5 ment of the crank;` and it consists in the constructions hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure l is a perzo spective of a triple-cylinder engine constructed in accordance with my invention. Fig. 2 is a vertical transverse section through one of the cylinders. Fig. 3 is a perspective of the seat for the cylinder detached. Fig. 4t is a per- 2 5 spective of the lower section of the cylinder. Fig. 5 is a perspective of the equaliZing-yoke for holding the cylinder to its seat. Fig. 6 is a perspective of the bed-plate or frame on which the engines rest, and Fig. 7 is a diagrammatie viewof the crank-shaft.

. Reference being had to the drawings and the letters marked thereon, A represents the bedplate or frame of the engine, which is provided y with a receiving-chamber, c, and a discharge- 3 5 chamber, b, separated by a vertical partition,

c, a supply-passage, d, and a discharge-passage, c.

B represents a detachable seat for the cylinder, through which are formed passages f g,

4o which communicate with the chambers a b,

respectively, formed in the bed-plate.

C represents the lower section of the cylinder, on which are formed trunnions h t', and to which the upper section, D, of the cylinder is bolted, as shown at k. The section C is also provided with a single passage, Z, which communicates with the passages f g. alternately as the cylinder vibrates in its seat. The lower end of the section C is convex or semi-cylindrical in form, and rests in a corresponding 5o cavity, m, in the detachable seat B.

The cylinders are held in their seats by means of an equalizing-yoke, which consists of side bars, a n, provided with recesses n a', which it over the trunnions 71l t', respectively, 55 and at their ends with rabbcts o o,i'or the reception of the end bars, p p, which are provided with corresponding rabbets, q q, which engage with the rabbcted portion ot' the bars n n and hold themagainst any lateral displace- 6o ment.

The bars p p are provided in their center with an aperture, through which a bolt, fr, passes, and said bolt is secured into or otherwise secured to the bed-plate A at s, and bc- 6 5 tween the head of the bolt r and the bar p maybe intcrposeda cushionsuch as a spiral spring, t, or a piece of rubber. By this construction of the equalizing-yoke the two trunnions are always subject to the same tension and the end of the cylinder wears evenly in the cavity m in the seat B.

When each trunnion is held by a separate yoke bolted down to the bed-plate, great careis required to adjust the yokes, and in practice it 7 5 has been found to be almost impossibleto keep up a true alignment oi' the cylinder and prevent one side wearing faster than the other.

E represents the crank-shaft, which consists of aseries of disks, u, connected at their cen- 8o ters by shafts which rest in boxes o, and wristpins w, to which the pistons y are connected. By this construction of the crank-shaft each disk a may be used as a driving-pulley with which to connect al separate machine and take 8 5 the power directly from the engine without the intervention of a countershaft and pulleys, as is the usual practice.

In Fig. l I have shown one of the disks u provided with radiating arms c and a rim, b', 9o to form a large driving-pulley, from which the power of the three engines is transmitted.

By connecting three engines to the wristpins of one erank-shait,as shownin Fig. l, the engines are perfectly balanced, and no deadcenters occur in the revolution of said shaft.

It will be observed that by the construction shown a very cheap, simple, and durable engine is prcduced, capable of being run at a very high-rate of speed and adapted for general use as a motor, and may be used with steam,

water, or any of the usual fluids applied for 5 the purpose.

The engine may be run in either direction, according lto the connection made with the supply-pipe for the motor-fluid.

Having thus fully described invention, What I claim is- I. In a vibrating-cylinder engine, the combination or" a chambered bed-plate, a detach- 2 5 the bed-p1ate,a cylinder provided With a conveX end and a single passage through said end, l

trunnions on opposite sides of the cylinder, and a yielding equalizing yoke engaging both trunnions and secured to the bed-plate, substantially as described.

3. A vibrating cylinder having a convex end and trunnions on opposite sides, in combination with a concave seat and an equalizingyoke consisting of side bars constructed to engage with the trunnicns and end bars connected to the side bars and to the bed-plate, substantially as described. v

4. An equalizing-yoke for an engine, consisting ef side bars having central cavities for engagement with trunnions and rabbets in 4o their ends, in combination with end bars having a central aperture and rabbets in their ends, and bolts for securing the yoke to a fixed portion of the structure, substantially as described. 4 5

In testimony whereofI affix signature in presenee of tW-o witnesses.
